If you mean by franchise, it just earned it's name for being overrated because it was supposed to finish the fight at halo 2. Technical side it almost looked like R:FoM except halo 3 was released a year after so why didn't it at least look like As Creed.
Another example....
The ever so popular and most overrated game FF series. It's either their innovations that pins down the game or the game pins down the innovation. But give 'em something they tried...
